The European defense sector is witnessing an unprecedented scale-up in manufacturing capacity, spearheaded by German industrial giant Rheinmetall. The Düsseldorf-based group is executing a continental expansion of its artillery ammunition production network at a pace unmatched by its peers. With four new facilities announced, billions in committed investment, and a bold revenue target of €14 to €14.5 billion by 2026, the company is navigating the largest capacity increase in its long history.
Securing Demand Amidst a Strategic Shift
This ambitious expansion is underpinned by strong political and financial tailwinds. Europe’s push for greater strategic autonomy, accelerated by uncertainties over long-term U.S. security commitments, continues to structurally elevate demand for defense materiel. The German federal budget for 2026 alone allocates €8.9 billion specifically for ammunition procurement. Rheinmetall’s current order backlog stands at a formidable €63.8 billion, providing the firm with an estimated six to eight years of planning visibility.
A Four-Pronged Pan-European Network
The centerpiece of this industrial offensive is a new facility in Unterlüß, Lower Saxony. An investment of approximately €500 million has established what the company describes as Europe’s largest artillery ammunition plant. Output is projected to reach 140,000 shells in 2026, scaling to an annual capacity of up to 350,000 units from 2027 onward. The ramp-up is de-risked by a framework contract with the German Bundeswehr worth up to €8.5 billion. An initial call-off of €880 million is explicitly designated to secure capacity during this critical build-out phase.
This German hub is being complemented by three additional strategic sites across Europe:
* Lithuania: An investment of up to €300 million for a plant scheduled to commence operations in 2026.
* Romania: A €535 million powder production facility slated for completion in 2029.
* Bulgaria: A joint venture where Rheinmetall holds a 51% stake in partnership with the government.
Collectively, this integrated network is designed to catapult the group’s annual production of 155-millimeter artillery shells from 70,000 units in 2022 to approximately 1.1 million by 2027—representing a staggering increase of over 2,000%.
Execution Remains the Key Challenge
While the demand picture is clear, the primary risk for Rheinmetall lies in the sheer complexity of the simultaneous capacity build-up. The company is tasked with integrating new production sites, shipyards, and diverse business models—a process that consumes significant time and resources. Management indicates that full operational synergies across this expanded footprint may not be fully realized until after 2027.
Investors will gain a crucial early insight into the progress of this plan when the group releases its Q1 2026 results on May 7, 2026. These figures will be scrutinized for evidence that the Unterlüß ramp-up and other integration activities remain on schedule. Furthermore, they will inform assessments of whether Rheinmetall’s even more ambitious long-term revenue target of €50 billion by 2030 remains achievable. The coming years will test the organization’s ability to translate monumental investment and robust orders into seamless execution and sustained profitability.
